The prestigious youth tournament has become a permanent fixture in the calendar for the Reds with the club winning the Premier Section in 2008 and 2009.
"It will be quite a young team in the Milk Cup this year as there will only be about two or three second-year scholars going," Academy head coach Paul McGuinness told ManUtd.com.
"It’s a very young team with a number of schoolboys so it will be interesting."
